I’m part of a Discourse forum that requires login. I get emails with a summary of recent topics.
Sometimes I click to open several of those in new tabs, but each tab says “you must sign in.” After I do, each tab goes to the home screen, not the discussion I was trying to reach. So I have to close them, go back to the email, and find what I was interested in again.
I think that if I’m redirected from a conversation to the login page, once logged in, I should be sent on to the page I originally requested.
